Vasily Gorbik 1471e96263 lib/crc32test: remove extra local_irq_disable/enable
commit aa4e460f0976351fddd2f5ac6e08b74320c277a1 upstream.

Commit 4d004099a668 ("lockdep: Fix lockdep recursion") uncovered the
following issue in lib/crc32test reported on s390:

  BUG: using __this_cpu_read() in preemptible [00000000] code: swapper/0/1
  caller is lockdep_hardirqs_on_prepare+0x48/0x270
  CPU: 6 PID: 1 Comm: swapper/0 Not tainted 5.9.0-next-20201015-15164-g03d992bd2de6 #19
  Hardware name: IBM 3906 M04 704 (LPAR)
  Call Trace:
